Abstract

Abstract A low cost sun screen device for use on motor vehicles is disclosed comprising a perforated polymer laminate sheet which is affixed to the interior surface of the vehicle rear window. The outermost surface of the laminate sheet includes artwork and other indicia formed thereon which when viewed by an observer through the rear window of the vehicle, simulates the appearance of a three-dimensional mechanical window louvre structure. The perforated laminate sheet provides an aesthetically pleasing, effective sunshield which reduces the temperature of the interior compartment of the vehicle by as much as forty percent while insuring that occupant visibility is not adversely affected.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 131 words
A sun screening device for use on a window of a motor vehicle comprising: a thin flexible sheet formed to be applied in a generally contiguous orientation to the interior surface of said vehicle window, said sheet formed of a material adapted to reflect and dissipate incident sunlight falling on said sheet; plural apertures formed through said sheet, said apertures sized to permit unimpaired vision through said sheet while maintaining a sufficient surface area for said sheet so that the majority of said incident sunlight falling on said sheet is screened from passage into the interior compartment of said vehicle; and indicia formed on said sheet adapted to generate a visual image simulating a rigid, three-dimensional window louvre structure when viewed from the exterior of said vehicle and through said window.
Claim 2
Dependent Claim 131 words
A sun screening device for use on a window of a motor vehicle comprising: a thin flexible sheet formed to be applied in a generally contiguous orientation to the interior surface of said vehicle window, said sheet formed of a material adapted to reflect and dissipate incident sunlight falling on said sheet; plural apertures formed through said sheet, said apertures sized to permit unimpaired vision through said sheet while maintaining a sufficient surface area for said sheet so that the majority of said incident sunlight falling on said sheet is screened from passage into the interior compartment of said vehicle; and indicia formed on said sheet adapted to generate a visual image simulating a rigid, three-dimensional window louvre structure when viewed from the exterior of said vehicle and through said window.
Claim 3
Dependent Claim 14 words
The sun screening device of claim 1 wherein said sheet comprises a polymer laminate.
Claim 4
Dependent Claim 33 words
The sun screening device of claim 2 wherein said polymer laminate comprises a first sheet portion formed of a polyvinyl chloride material and a second sheet portion formed of a polyester fabric material.
Claim 5
Dependent Claim 20 words
The sun screening device of claim 3 wherein said indicia is formed on said second sheet portion of said laminate.
Claim 6
Dependent Claim 14 words
The sun screening device of claim 4 wherein said indicia is formed by silk-screening.
Claim 7
Dependent Claim 16 words
The sun screening device of claim 4 wherein said indicia is formed by a half-tone printing.
Claim 8
Dependent Claim 15 words
The sun screening device of claim 5 wherein said silk-screening comprises a three-color silk-screening process.
Claim 9
Dependent Claim 21 words
The sun screening device of claim 4 wherein said plural apertures are equidistantly spaced along the surface of said polymer laminate.
Claim 10
Dependent Claim 22 words
The sun screening device of claim 8 wherein said plural apertures are sized to be approximately 1/32 of an inch in diameter.
Claim 11
Dependent Claim 169 words
A sun screening device for use on the rear window of a motor vehicle to reduce the temperature of the interior compartment of said motor vehicle comprising: a thin flexible laminate sheet comprising a first sheet portion formed of a polyvinyl chloride material and a second sheet portion formed of a polyester fabric material, said laminate sheet sized to be applied in a substantially contiguous orientation to the surface of said rear window exposed within the interior compartment of said vehicle and adapted to reduce the passage of incident sunlight falling on said rear window into said interior compartment of said vehicle; a plurality of apertures formed through said laminate sheet each sized to permit vision through said laminate sheet from said interior compartment of said vehicle; and indicia formed on said laminate sheet representing a louvre structure, said indicia, when viewed through said rear window from a location exterior of said vehicle, adapted to render a visual image simulating an exterior mounted three dimensional mechanical window louvre structure.
Claim 12
Dependent Claim 169 words
A sun screening device for use on the rear window of a motor vehicle to reduce the temperature of the interior compartment of said motor vehicle comprising: a thin flexible laminate sheet comprising a first sheet portion formed of a polyvinyl chloride material and a second sheet portion formed of a polyester fabric material, said laminate sheet sized to be applied in a substantially contiguous orientation to the surface of said rear window exposed within the interior compartment of said vehicle and adapted to reduce the passage of incident sunlight falling on said rear window into said interior compartment of said vehicle; a plurality of apertures formed through said laminate sheet each sized to permit vision through said laminate sheet from said interior compartment of said vehicle; and indicia formed on said laminate sheet representing a louvre structure, said indicia, when viewed through said rear window from a location exterior of said vehicle, adapted to render a visual image simulating an exterior mounted three dimensional mechanical window louvre structure.
Claim 13
Dependent Claim 63 words
The sun screening device of claim 10 wherein said indicia comprises: a first indicia portion representing plural louvre shutters, which are vertically spaced and extend in a generally parallel orientation along the length of said laminate sheet; a second indicia portion representing a void formed between adjacent louvre shutters; and a third indicia portion representing a side transition between said plural louvre shutters.
Claim 14
Dependent Claim 55 words
The sun screening device of claim 11 wherein said first indicia portion is formed in a first color, said second indicia portion is formed in a second color, darker than said first color, and said third indicia portion is formed in a third color darker than said first color but lighter than said second color.
Claim 15
Dependent Claim 25 words
The sun screening device of claim 12 wherein said first color is gray, said second color is black and said third color is dark gray.
Claim 16
Dependent Claim 19 words
The sun screening device of claim 12 wherein said first, second, and third indicia portions are formed by silk-screening.
Claim 17
Dependent Claim 22 words
The sun screening device of claim 12 wherein said first, second, and third indicia portions are formed by a half-tone printing process.
